>>3 the guy/girl has a great idea here. You can also add that as time passes by she started to dream of it even if she's awake and eventually it happens in reality. The story you have really suits the mystery and for the romance, you might want to think already on who's the guy that she might end up getting together with too help you with the flow of the rest of the story. I hope we got to help you and try not too rush too.
*The story kind of reminds of the myth Pandora box. :D
Good luck making your story then.. X]
